Wow, that´s something!
I just found, at www.qajaqusa.org, pictures of Ken Taylor and Duncan Winning: The two man where the roots of the AnasAcuta started.
As I look at it, it´s those two man who, together with Derek Hutchinson, initiated the development of modern seakayaks until now; well done my boys! 
Looking at the pictures, these man, being in there 60-70ths, are still looking very fit.
